This invention relates to Iissul improvements in mold-ing -frnisraiid particularly to molding fornireV fer rise vin constructing hollow concrete walls.

One obj ect1 of the presentl invention is provide a form which is easily placed position to permit the pouring of the concrete thereinto, and which may be easily and quickly removed after the concrete has set.

Another object is to provide a novel and improved means for spacing the inner portions of the form in proper relation.

A further object is to provide novel and improved means for retaining the external members of the form in proper position while molding the wall and which will serve, after the Wall is finished, to space and brace the wall.

Other objects and advantages will be apparent from the followingr description when taken in connectionwith the accompanying drawing.

In the drawing:

Figure 1 is a top plan view of the improved hollow wall molding form in the position it assumes when the concrete is to be poured.

Fig. 2 is a vertical transverse sectional view taken on the line 2 2 of Fig. 1.

Fig. 3 is a vertical longitudinal sectional view taken on the line 3-3 of Fig. 1.

Fig. 4 is a top plan view of a fragment of the finished wall.

Referring particularly to the accompanying drawing, the mold includes the outer members 10 and the inner members 11, the latter of which are made up of the plurality of vertically disposed and jalousied strips which are secured together at their overlapping edges,as shown at 12.

Disposed horizontally between the two inner sections 11 of the form are the spacing members which consist of the pairs of strips 13, having the longitudinally extending bev- `lenivr Fn Honiow MOLDED WALLS.

When the concrete has properly set, the eiipsfare releaseidiand` thefstripsl iseparated and withdrawn from between the sections 11 of the form, when said inner sections may be moved toward each other and away from the wall faces molded thereby.

To hold the inner and outer portions of the wall from collapsing there are provided the spacing and tying members which consist of the strips of metal 16 each having a transverse headed pin 17 in each end, and to each of these pins is secured a wire 18, the other ends of the wires being passed between certain of the boards of the outer mold section 10 and secured to an upright 19 which is disposed against the outer face of the said outer section. These strips 16 exten-d across the space in the center of the wall and have their ends embedded in the concrete wfhich is molded between the inner and outer mold sections, and remain therein when the mold sections are taken down. In the overlapping edges of certain of the boa-rds of the sections 11 there are formed the notches 20 in which are received the in- 'termediafte portions of the tying strips 16. These boards of the said mold sections are separated, when the sections are taken out so that the said seetions'may be disengaged from the strips and thus permit the strips to remain emfbedded in the wall.

Before beginning the wall a foundation 21. is formed, and secured on the upper face of this foundation is the strip 22 which spaces the lower ends of the inner sections 11 apart, as cleariy shown in Fig. 2, and in Fig. 3 of the draw'in If desired, when t e mold sections are taken down, the outer ends of the wires 18 maybe left protruding from. the faces of the 110 wall for the purpose of attaching ornemen tation thereto, or seid wires may `be twisted or tied together and then the surplus ends out o.

VVha-t is claimed is:

1. A form for molding hollow concrete wells including a pair of outez` spaed mold sections, a peir of Vinner mold seetlons spel/cedV from the outer sections and from eaeh other, each of the inner sections being formed of a series of vertical jalousied strips secured togethez at their overlapping edges, well tying spacing members carried by and extending through the inner sections, and horizontally disposed fbeveled strips extending between and holding the inner sections in spaced relation to each other.

2. A 4form for hollow molded walls including outer seotions, inner sections spaoed therefrom land from eeoh other, Ineensex- 'tending through the inner sec-.tions to tie the Well together and to be embedded in the well, beveled abutting stripsY disposed horizontally 'between 'the inner sections, and clips embracing the ends of the pairs of strips to hold them` in proper position between the mold sections.

3. mold for a hollow concrete well including outer spweed mold sections, inner mold seotionefspaced from the rst sections and from eeeh other, sai-d inner sections being formed with 'e series of vertical jalousied boards,"'ceitain of the iboerds having elining notches in their overlapping edges, tie strips extending through said notches and a.r ranged to be embedded in the nished wall, iiexible meni'bers secured to the ends of the tie Vmembers and extended through the outer mold sections, and vertical braces disposed against the outer faces of the outer mold sections and having the outer ends of the exillfe members secured thereto.

In testimony whereof we affix our signo.- tures, in the presence of two witnesses.
